Title: Collecting method of metal from industrial by-product
Inventor: ABE HIDEKI
IPC: C22B7/00
Filed: 1982-02-15
Abstract: PURPOSE:To collect Cu and valuable metals economically and in a high yield, by performing a leaching treatment of industrial by-products containing Cu and Pb, Zn, Fe, As, Ag, Cd, etc. together with solid sulfides under gaseous SO2 atmosphere by sulfuric acid. CONSTITUTION:The industrial by-products are subjected to the leaching treatment using sulfuric acid in the presence of solid sulfide of >=1 molecular ratio to the amount of Cu therein and under gaseous SO2 atmosphere at >=70 deg.C temp. Cu is precipitated selectively as copper sulfide, Zn, Fe, As, Cd etc. are eluted into the liquid and Pb, Ag are precipitated together with Cu as sulfides. The precipitates are refined to recover the metals. After separation of the precipitates, the solution is cooled to collect arsenious acid crystals. Then arsenic sulfide is obtained by gaseous H2S to perform dearsenation. The solution is neutralized with Na2CO3 to remove gypsum, Zn, Cd is recovered as the sulfides by gaseous H2S and Fe3O4 is precipitated by oxidizing air so as to remove iron.

Filed: 1984-02-09
Abstract: PURPOSE:To improve the recording resolution with simple constitution by filling a gap between main dots with an interpolation dot arranged while being shifted by a half pitch to the main dot and controlling an exposure energy of the interpolation dot to a prescribed amount. CONSTITUTION:The timing of read for memories 71 and 72 is controlled that the interpolation dot is shifted slightly (e.g., 50mum) in the horizontal scanning direction to the main dot. A laser drive circuit 5 is applied with correction so that the exposure energy of th interpolation dot is brought into a prescribed value being slightly smaller than the exposure energy of the main dot. Thus, the arrangement between the main dot D1 and the interpolation dot D2 is formed to a pattern as shown in Fig. and also the interpolation dot D2 is formed to a dot smaller than the main dot D1. Then the overlapped part between the main dot D1 and the interpolation dot D2 is less and proper exposure is attained.

Filed: 1980-02-26
Abstract: PURPOSE:To discriminate the deterioration of a plating bath previously from the plating strength of test pieces, by plating the test pieces by permitting a bipolar phenomenon, which more intense than that occurring in actual operation, to occur by changing over a switch. CONSTITUTION:In plating bathtub 1, a couple of electrodes 2 and 3 are arranged and between both the electrodes, test pieces 4 and 5 are arranged.

Filed: 1997-02-06
Abstract: PROBLEM TO BE SOLVED: To reduce the time required for a designing operation by installing a step that computes a change in interatomic potential energy in a region near the interface between a thin film and a substrate due to environmental molecules. SOLUTION: The initial plan of an on-substrate thin-film formation condition is set, and an on-substrate thin-film formation simulation is performed on the basis of the plan. Then, environmental molecules are brought close to a part near the interface between a thin film and a substrate, and an energy barrier which causes an interface defect between the thin film and the substrate in this case is computed. Then, the improvement plan of the thin-film formation condition based on the computed result of the energy barrier is output. As an execution example, on the basis of the initial plan of the on-substrate thin-film formation condition, film-constituent atoms 6 are deposited on a substrate 1 which is constituted of inside-substrate atoms 2, and a film 5 is formed.  Then, environmental molecules 8 are brought close to a part 7 near the interface 4 between the substrate 1 and the film 5, a change in bonds 3 is taken into consideration, and an energy barrier which generates and grows an interface defect is computed. Thereby, the time which is required to quantitatively compare various plans of a thin-film formation condition which is important for a designing operation is reduced, and the time for the designing operation can be shortened.
